KwiFraunhofer Institute for Machine Tool and Molding Technology IWU, abaphandi baphuhlisa itekhnoloji ephucukileyo yokuvelisa iinjini zeeseli zamafutha ukuququzelela ukuveliswa kobunzima okukhawulezayo, okunexabiso eliphantsi. Ukuza kuthi ga ngoku, abaphandi be-IWU baqale bajolisa ngqo entliziyweni yezi njini kwaye bafunda iindlela zokwenza iipleyiti ze-bipolar kwiifoyile zentsimbi ezibhityileyo. Kwi-Hannover Messe, iFraunhofer IWU iza kubonisa ezi kunye neminye imisebenzi ethembisayo yophando lwe-fuel cell injini kunye neSilberhummel Racing.
Xa kuziwa ekunikezeni amandla iinjini zombane, iiseli zamafutha yindlela efanelekileyo yokongeza iibhetri ukunyusa uluhlu lokuqhuba. Nangona kunjalo, ukwenza iiseli zepetroli kuseyinkqubo ebiza imali eninzi, ke ngoko kusekho iimodeli ezimbalwa kakhulu ezisebenzisa le teknoloji yokuqhuba kwimarike yaseJamani. Ngoku abaphandi beFraunhofer IWU basebenzela isisombululo esineendleko eziphezulu: “Sisebenzisa indlela epheleleyo yokufunda onke amacandelo akwi-injini yeeseli zamafutha. Into yokuqala yokwenza kukubonelela nge-hydrogen, echaphazela ukukhethwa kwezinto eziphathekayo. Ibandakanyeka ngokuthe ngqo ekuveliseni amandla eeseli zepetroli kwaye inabela nakwiseli yamafutha ngokwawo kunye nolawulo lobushushu besithuthi siphela.” Umphathi weprojekthi ye-Chemnitz Fraunhofer IWU uSören Scheffler wachaza.
Kwinyathelo lokuqala, abaphandi bagxile entliziyweni yayo nayiphi na injini ye-fuel cell: "i-fuel cell stack." Apha kulapho amandla enziwa khona kwiibhetri ezininzi ezipakishiweyo ezenziwe ngeepleyiti ze-bipolar kunye ne-electrolyte membranes.
Scheffler wathi: “Siphanda ngendlela yokutshintsha iipleyiti zegraphite bipolar zamandulo ngokufaka iifoyile ezicekethekileyo zentsimbi. Oku kuya kwenza ukuba izitaki ziveliswe ngobuninzi ngokukhawuleza nangoqoqosho kwaye zonyuse kakhulu imveliso. ” Abaphandi nabo bazibophelele ekuqinisekiseni umgangatho. Khangela yonke icandelo kwi-stack ngqo ngexesha lenkqubo yokuvelisa. Oku kukuqinisekisa ukuba kuphela iindawo ezihlolwe ngokupheleleyo ezinokungena kwi-stack.
Kwangaxeshanye, iFraunhofer IWU ijolise ekuphuculeni ukukwazi kwetshimini ukuziqhelanisa nokusingqongileyo kunye neemeko zokuqhuba. Scheffler wacacisa: “Ingcinga yethu yeyokuba ngoncedo lwe-AI, uhlengahlengiso oluguquguqukayo lwemekobume lunokonga i-hydrogen. Nokuba isebenzisa i-injini kumaqondo obushushu aphezulu okanye aphantsi, okanye isebenzisa i-injini ethafeni okanye kwindawo yobushushu obuphezulu, iyakwahluka. Okwangoku, isitaki sisebenza kuluhlu olumiselweyo olumiselweyo, olungakuvumeli oko kuxhomekeke kokusingqongileyo. ”
Iingcali ezivela kwiLebhu yeFraunhofer ziza kubonisa iindlela zabo zophando kumboniso we-Silberhummel kwi-Hannover Messe ukususela ngo-Aprili 20 ukuya kwi-24th, 2020. I-Silberhummel isekelwe kwimoto yomdyarho eyenzelwe yi-Auto Union kwi-1940s. Abaphuhlisi be-Fraunhofer IWU ngoku basebenzise iindlela ezintsha zokuvelisa ukuze bakhe ngokutsha isithuthi kunye nokudala ababonisi beteknoloji bale mihla. Injongo yabo kukuxhobisa iSilberhummel nge-injini yombane esekwe kubuchwephesha beeseli zamafutha. Le teknoloji iboniswe ngedijithali kwi-Hannover Messe.
Umzimba weSilberhummel ngokwawo ukwangumzekelo wezisombululo zokwenziwa kwezinto ezintsha kunye neenkqubo zokubumba eziphuhliswe ngakumbi nguFraunhofer IWU. Nangona kunjalo, kugxilwe apha kukwenza ixabiso eliphantsi kwiibhetshi ezincinci. Iipaneli zomzimba we-Silberhummel azenziwanga ngoomatshini abakhulu besitampu, ezibandakanya imisebenzi enzima yezixhobo zentsimbi. Endaweni yoko, kusetyenziswa umngundo obhinqileyo owenziwe ngomthi ekulula ukuwulungisa. Isixhobo somatshini esenzelwe le njongo sisebenzisa i-mandrel ekhethekileyo ukucinezela ipaneli yomzimba kancinci kancinci kwisikhuseli somthi. Iingcali zibiza le ndlela "i-incremental shape". “Xa kuthelekiswa nendlela eqhelekileyo, nokuba sisikhuselo, ihood, okanye icala le tram, le ndlela inokuvelisa amalungu afunekayo ngokukhawuleza. Umzekelo, ukwenziwa kwezixhobo eziqhelekileyo ezisetyenziselwa ukwenza amalungu omzimba Kungathatha iinyanga ezininzi. Sidinga ngaphantsi kweveki ukusuka ekwenziweni kwesikhunta somthi ukuya kuvavanyo lwephaneli egqityiweyo, ”utshilo uScheffler.
